Smoking is linked to a higher risk of amnesia, a memory impairment. This population-based study in Iran found smokers had increased odds of experiencing amnesia compared to non-smokers.
Area of Science:
- Neuroscience and Cognitive Science
- Public Health and Epidemiology
Background:
- Amnesia is a cognitive impairment affecting memory retrieval and acquisition.
- Limited research exists on amnesia risk factors, particularly in Iran.
- Smoking is a potential risk factor for cognitive decline and amnesia.
Purpose of the Study:
- To explore risk factors associated with amnesia.
- To investigate the relationship between smoking and amnesia.
Main Methods:
- Population-based cross-sectional study conducted in southwest Iran (2016-2018).
- Data collected from 35-70 year olds on demographics, socioeconomic factors, and medical history (stroke, epilepsy, head trauma).
- Multiple logistic regression used to analyze the association between smoking and amnesia, controlling for confounders.
Main Results:
- Amnesia prevalence was 4.2% in the study population (mean age 48.83±9.20 years).
- Smokers had significantly higher odds of amnesia (adjusted odds ratio=1.52).
- Age, education, residence type, stroke, epilepsy, and trauma history were also associated with amnesia.
Conclusions:
- A direct correlation between smoking and amnesia was identified.
- Future longitudinal studies are recommended to understand the underlying mechanisms.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
